Description

电路组件和结合这种组件的电子设备
技术领域
本发明涉及电路组件和结合这种组件的电子设备。特别是，本发明用于(但不限于)本领域中通常称为翻盖电话或蛤壳式电话的无线通信设备。
背景技术
无线通信设备需要一个或多个天线，用于发射和接收无线电通信信号。例如，在900MHz频带GSM系统上提供服务的网络运营商需要依靠1800MHz频带的DCS系统。因此，诸如蜂窝无线电话的无线通信设备应该能够至少在这两个频率上通信。
如今的消费需求是通常具有内置天线而非用户可见的天线棒(antenna stub)的紧凑型无线通信设备。然而，内置天线的灵敏度和性能会受到设备电路的显著影响。通常通过将内置天线放置在与设备电路隔开的指定区域来提供减轻该问题的方案。这种方案增加了设备尺寸，与消费需求相逆。
在本说明书中，并且包括权利要求书在内，术语“包括”、“包含”或类似术语意指非排他的包括，从而包括一列元件的方法或装置不仅包括这些元件，还包括没有列出的其他元件。
发明内容
根据本发明的一个方面，提供一种电路组件，其包括电路衬底、导电条(conductive runner)和至少一个接地面。具有安装到所述电路衬底并电耦合至所述条的电子电路。一个电子单元电耦合到所述电子电路的至少一部分。还有至少一个单极元件通过介电底座安装到电子单元的表面上，该介电底座接近衬底的边缘。
所述单极元件可适当地是平的导电部件。
适当地，所述单极元件可以沿单极面排列。
优选地，所述单极元件可被支撑在附着到所述介电底座的单极衬底上。
优选地，可具有一个以上的单极元件，从而提供安装在所述单极衬底上的多个单极元件。
适当地，所述单极元件可全部是平的导电部件。
适当地，所述单极元件可全部沿所述单极面排列。
优选地，所述衬底可以安装在所述电子单元的所述表面上。
适当地，所述单极面可平行于所述接地面的平坦表面。
优选地，所述单极面距离所述底座比所述接地面更远。
优选地，在所述电路衬底相对于所述接地面的平面图中，在所述单极元件和电路衬底之间可具有非重叠关系。
优选地，所述电子单元可以是显示单元。适当地，所述显示单元可以是液晶显示屏。
优选地，所述介电底座可具有最大为5的介电常数。
适当地，所述介电底座可具有最大为1.5的介电常数。典型地，所述介电底座由聚苯乙烯形成。
根据本发明的一个方面，提供一种电子设备，其包括电路衬底、导电条和至少一个接地面。电子电路安装到所述电路衬底并电耦合至所述条。一个电子单元电耦合到所述电子电路的至少一部分。至少一个单极元件通过介电底座安装到电子单元的表面上，该介电底座接近衬底的边缘。还具有互补单极元件，由此与所述至少一个单极元件结合形成与所述电子电路相关的双极天线。
适当地，该无线通信设备可以包括上述任何整体或特征。
附图说明
为了使本发明易于理解并产生实际效果，将参考附图对示出的优选实施例进行说明，其中：
图1是根据本发明的电流组件的侧视图；
图2是图1的电路组件的平面图；
图3是结合图1的电路组件的无线通信设备的侧视图。
具体实施方式
在附图中，不同附图中的相同标记用来表示相同的元件。参考图1和图2，示出了电路组件1，它包括可折叠印刷电路板2形式的电路衬底、导电条3和至少一个接地面4。接地面4是在印刷电路板2上或在印刷电路板2内形成的导电片。电路组件1还具有电子电路5，它安装在印刷电路板2上，电极或连接器通常通过导电焊盘电耦合到条3，如本领域技术人员显而易见的。还具有电子单元，通常是液晶显示屏6，(直接或间接)电耦合到电子电路5。
对于需要在GSM和DCS频率上通信的双频带无线通信设备，电路组件1具有两个基本单极元件，它们是基本单极元件7和基本单极元件8，这些单极元件通过介电底座10安装在液晶显示屏6的表面9上。介电底座10接近印刷电路板3的边缘11，介电底座10通常由聚苯乙烯形成，介电底座10理想地具有最大为1.5的介电常数，然而可以使用更高的介电常数，最大直到5。
两个单极元件7和8都是提供四分之一波长天线的平的导电部件，其具有互补的四分之一波长天线，从而与单极元件7、8中的任一个组合起来形成与电子电路5相关联的双极天线。单极元件7、8沿单极面12排列，并且单极元件7、8被支撑在附着到介电底座10的单极衬底13上。
印刷电路板2安装在液晶显示屏6的表面9上，该表面是液晶显示屏6能够显示标记的显示表面14的反面。另外，单极面12平行于接地面4的平坦表面，该平坦表面沿虚线16标识。另外，单极面12距离液晶显示屏6比接地面4更远。具体参考图2示出的印刷电路板2的平面图，在单极元件7、8和印刷电路板2之间是非重叠关系。
参考图3，示出了无线通信设备30形式的电子设备，其结合有图1的电路组件。示出的无线通信设备30是蛤壳式电话，包括两个外壳部分31和32，它们关于枢轴35彼此枢轴式安装。部分31容纳电路组件1(以虚线示出)，部分32容纳电耦合至电路组件1的收发信机电路板34(以虚线示出，包括互补四分之一波长天线)、键盘区域33和电池盒37。
从平面图中看，本发明提供了单极元件7、8和印刷电路板2之间的非重叠关系。这有利地减轻了单极元件7、8的一些灵敏度和性能方面的问题。此外，电路组件1的位置和结构削弱了与内置天线相关的间隔需求。因此，本发明可以提供减小的天线空间布置，从而有助于减小无线通信设备30的尺寸。
本详细说明仅提供了优选实施例，并不欲限制本发明的范围、应用或配置。而且，优选实施例的详细说明为本领域技术人员提供了能够实施本发明优选实施例的描述。应该理解，可以进行各种功能和元件配置的改变，而不脱离在所附权利要求中提出的本发明的要旨和范围。
